                                According to the UK's National Physical Laboratory, the standard convention dictates that 12 PM is noon (midday), while 12 AM is midnight, a point of confusion for many people. In simple terms, no, it is not 12 am at lunch, because lunch happens in the middle of the day. This simple error, however, can cause scheduling mistakes and communication breakdowns in both personal and professional life.
